Letters Patent No. 70,319, dated October 29, 1867.

IMPROVED CHAIR POR SGHOLS, 6to.

Be it known that I, SAMUEL C. BROWN, of Richmond, Wayne county, Indiana, have made a new and useful Improvement in Chairs vfor Schools and other uses; and that I dol hereby declare that the following is a full and exact description of the construction thereof, reference being had to the accompanying drawings, in which Figure 1 is :L perspective view, in which A represents the4 seat or chair. A represents the oor. B and B! represent the legs or supports of the chair. C represents the bolt connecting the parts B and B. D represents the elastic packing between the parts B and 'B'. E represents the elastic washer between vthe disk ofthe piece B and the nut C.

In setting up the chair, B is screwed to the oor, and B is screwed to the chair, or vice versa. The elastic packingD is placed between the parts B and B', and the bolt C is placed in position, connecting the disks of the pieces B and B', The elastic washer E is placed-between the nut C and the disk of the piece B or B', es may be, the object being to relieve the seat of its rigidity, and also relieve the screws of the strain usually thrown upon them. Y

`The holes through the top of the support B', and also through the bottom of the part B, through which the bolt C is intended to pnss,'must be mede tapering towards the intermediate washer` so as to permit the oscillation of the seat without too great strain upon the bolt. i

I wish to claim and secure by Letters Patent- The combination of the seat-supports B and B with the spring D, elasticwasber E, and bolt C, and nut C', constructed and arranged to operate substantially as and for the purpose set forth.

SAMUEL C. BROWN.
